v0.3.0 is out

[binary-manu]

A new version of the playbook is out.

v0.3.0 aligns with the upstream's decision to switch to yescrypt for password hashing. This made some configuration variables useless.

Work was also done to allow testing the playbook via CI, to get a more comprehensive set of tests when new upstream images/boxes are released. It should be now easier and faster to catch bugs, maybe before people report them.

Since these changes introduced some backward-incompatibilities, it was good moment to make a version bump to v0.3.0 and abandon hard compatibility with v0.2.x. As part of that, some deprecated stuff was also removed. have a look at the migration instruction if you want to bring your configuration to v0.3.0.
